Abstract: A subframe for retrofitting an existing roof with a new roof is disclosed. In some embodiments, the subframe comprises a base, a first and second longitudinal flanges, a first wall extending between the base and the first longitudinal flange, a second wall spaced apart from the first wall and extending between the base and the second longitudinal flange, and a traversely-oriented punch out passing through the base, the first wall and the second wall. The punch out is configured to receive a rib of the existing roof. Once installed on the existing roof and coupled to the new roof, the subframe and new roof form an enclosed, self-supporting structure with increased structural capacity and stability in comparison to conventional retrofitted roof systems.

Abstract: A gutter system characterized by a continuous snap lock hinge connection between a gutter and hanger therefor which allows the gutter and hanger to be relatively angularly adjusted in the field for use with different roof configurations, and which then is secured against hinged movement by bonding to provide a continuous rigid support for the gutter as well as a continuous water seal between the gutter and hanger. The hanger includes an anchoring flange having a reversely under-turned edge portion forming a hook; whereas each of the gutter side walls has an inwardly-turned top edge terminating at an enlarged bead adapted to be transversely snapped into the bight of the hook for hinged movement therein. The interengaged hook and bead allow the gutter and hanger to be relatively angularly adjusted as desired until an adhesive interposed between mating surfaces thereof sets or cures to form a rigid bond that holds the gutter and hanger in the desired adjusted angular relation.
